FRUTI-I, orcIIIoAGo, ILLINOIS, AssIenoR To weare 'sn' ncr c "oer/ream,INCORPORATED, OF NEW YORK, N. Y., A CORPORATION 01 NEW YORK LIQUID SPRAYDEVICE Application filed December 10, 1930.

This invention relates to liquid spray devices, and more particularly todevices wherein a liquid and a gas are brought into contact for thepurpose of purifying the gas or for other purposes. D

An object of the invention is to provide a liquid spray device ofsimplified construction which shall be inexpensive to manufacture andwhich is non-clogging and may be #1 readily inserted in and removed froma gas conduit.

In its preferred form, the invention comprises a liquid conduit mountedwithin a gas conduit and having attached to its discharge end adeflector designed to deflect the liquid into the form of a circularsheet which extends transversely of the gas conduit, so that the gaspassing through the gas conduit is necessarily brought into contact withthe sheet of liquid. The construction of the deflector is of asimplified non-clogging design, and its maximum diameter isapproximately the same as the diameter of the liquid conduit, whichfacilitates the assembling and disassembling of the apparatus.

The invention will be more fully understood from the followingdescription, taken in connection with the accompanying drawing, in whichFig. 1 is a sectional view of adevice embodying the invention, showingthe liquid conduit in elevation;

Fig. 2 is a vertical sectional View taken on the line 22 of Fig. 1;

Fig. 3 is a view of the liquid conduit and deflector as viewed from thebottom of Fig. 2, and

Fig. 4 shows the deflector in an intermediate stage of manufacture.

Referring now to the drawing, the device comprises a gas conduit throughwhicn gas may be passed either upwardly or downwardly as desired.Secured within the conduit 10 by any suitable securing means (not shown)is a liquid conduit 12, the lower end of which is slotted atdiametrically opposite poin'ts as indicated at 14 to receive a deflector16. The deflector has a pair of spaced upwardly extending integral arms18 which fit into the slots 14 and are preferably secured therein Serialno; 501,225.

by pinching the end of the conduit 12 to compress the arms rigidly inposition, although soldering, welding or other means may be employed forsecuring the arms in'place.

As shown in Fig. i, the deflector is formed from a sheet metalblank, bystamping or otherwise, the ends ofthe blank being roundthe opposite endof the aperture to holdthe arms 18 rigidlytogetherl lVhen assembled, thetransverse dimensions of the deflector should be substantially equal totire transverse dimensions of theconduit 12, and-the baffles 20 shouldbe spaced from thelower end of the conduit 12 by a distance :not'substantially less than said transversedimensions.

In operation, water-or other liquid is passed downwardly through theliquid conduit 12 and strikes the baffles 20-which form-it into acircular sheet which extends over the entire cross-section of the gasconduit 10, sotha-t gas passing therethrough necessarily contacts withthe liquid ofthe sheet.

The device may be advantageously used as a sparkarres'ter in 'connectionwith a flamemaking wire enameling apparatus, in which case the gasconduit 10 will convey exhaust gases from the apparatus, some of whichgases may be the products of incomplete combustion and thereforeexplosive, and the gases may also contain some floating particles ofburning solid matter, which will be extinguished by the sheet of liquidproduced by the ballies 20. The liquid employed in such case willordinarily be water, and it is frequently desirable to circulate thewater over and over again, which causes the liquid to accumulate acertain amount of scum and other solids collected from the gases. Withthe device of the present invention, however, such solids do not collectat the deflector nor obstruct the same, since any solid matter whichwill pass the conduit 12 will also pass the deflector. This is becausethe width of 100 the aperture 22 is the same as the inner diameter ofthe liquid conduit 12, and because the bafiles 20 are spaced from thelower end of the conduit 12 by a distance not substantially less thansaid inner diameter.

In addition to its use as a spark arrester, the device may be used forpurifying or cooling gases, or in any relation where it is de sired tobring a gas and a liquid into contact. The invention is therefore notlimited to the precise constructional and functional features abovedescribed, but may be modified without departing from the spirit thereofas defined in the following claims.

15 What is claimed is:

1. In a liquid spray device, a liquid conduit having a slotted end, anda deflecting member secured to said end and comprising arms fixed in theslots of the liquid conduit and bafiles positioned in alinement with theconduit, said arms extending beyond said conduit and lying substantiallywholly be tween the extended interior and exterior surfaces of theconduit wall and said baflles having an area substantially equal to thecrosssectional area of the conduit.

2. A liquid spray device comprising a cylindrical open ended pipe and atransverse baffle spaced from the end of the pipe and supported solelyby connections lying substantially wholly inside the extension of theouter surface of the pipe and outside the extension of the inner surfaceof the pipe, the end of said pipe being slotted and said connectionsconsisting of arms secured within said slots.

3. A liquid spray device comprising a pi e having a slotted end and asheet metal ba e having abutting semi-circular portions and integralside strips folded to form supports, the bights of said folds beingsecured in said slots.
